RE: How to 'glass wing join without clogging torque rods?
Charles,
Do the underside of the wing first. This is where the main stress point is anyway.
When you lay out the strip of glass cloth, start around 1/2" behind the torque rods, work your way around the underside and then once you come around the leading edge and up to the topside, stop another 1/2" short of the torque rods.
This will give you ample strength for your Trainer 40
Hope this helps
